13 Claims. (Cl. 61-46.5)

The present invention relates to a convertible working platform barge and submerged marine assembly for subaqueous operations.

This application is a continuation of my co-pending application Serial No. 460,598, filed October 6, 1954, now abandoned.

An important object is to provide a marine unit assembly composed of floating and submergible members, such as two barges or an upper buoyant barge and a coacting structural frame or truss movable to assume a stacked position when the unit assembly is being floated from place to place, and to provide a marine groundengaging base and a working platform above the level of the Water, when the assembly is in its marine operative position. The barges and the structural frames which are arranged in superimposed relation are provided with vertical aligned guide openings or wells through which extend caissons or supporting members. Certain of these caissons extend through the openings in the lower barge or structural frame so as to be embedded or anchored into the marine ground. Others Of the caissons extend through the upper barge and are connected to the lower barge or a structural frame member. Thus, it will be seen that each floating unit when the barges or members are in their stacked position, are transportable from place to place and that the upper barge may be readily converted into a working platform when raised above the water level on the supporting members by jacking mechanism operable thereon. Further, the lower or bot-tom barge or the structural frame member may be submerged so as to rest on the marine bottom and provide a strong, stable, supporting base for maintaining the working platform and its associated parts in a firm operative position irrespective of the irregularity of the contour of the marine ground or bot-tom on which it rests.

A further object consists in providing an improved method for erecting a convertible barge and submergi-ble floating assembly over a body of water, which includes floating at least two barges or members stacked one on top of the other to the desired location. The barges or members are provided with vertical registering openings through which extend caissons or the like. Certain of the caissons are arranged to extend through the openings in the lower barge or member so as to be embedded into the marine ground to prevent lateral displacement of the unit assembly when the upper or top barge is raised and maintained above the water level. The other caissons extend loosely through the upper barge and are connected to a lower barge or member so as to be movable therewith. After the lower barge is moved firmly into engagement with the marine ground, the upper barge which now constitutes the working platform, is raised above the level of the water to provide a structure capable of being efficiently used for drilling oil or other wells, driving piles,

building of permanent structures, installing temporary or permanent docks, and for various other marine uses in which a working platform over water is required, such as a dry dock for repairing boats and the like.

A further object comprehends the provision of an improved submergible marine assembly and method of erecting the same, in which three watertight barges or members are arranged normally to be stacked so as to be transported from place to place. The floating unit assembly may also include one buoyant barge with two vertically spaced metal frames or trusses positioned below the barge. The barges and structural frames are provided with vertical openings through which extend caissons or other similar tubular supporting members. Certain of the caissons extend through all of the barges so as to penetrate the marine ground in order to maintain the barge assembly in a fixed or anchored position. Other of the caissons extend through the upper barge and an intermediate barge or member and are connected to the bot- 7 tom barge or member while the remaining caissons extend loosely through the upper barge and are connected to an intermediate barge or structural frame member. Thus, it will be seen that simple, efficient and economical means are provided for converting a floating barge assembly into a working platform that is firmly supported by means engaging the marine bottom, when the Workiug platform is raised above the water. The intermediate barge or member serves to impart the desired strength, rigidity, and stability to the barge assembly so that it may efliciently support the heavy working platform and its associated parts in a fixed position during the marine operation.

Referring to the drawings, the convertible floating barge and submergible marine assembly or floating unit, as shown in FIGURE 1, includes an upper buoyant barge and a lower, hollow barge 11 of any suitable size and shape depending upon the purpose for which the assembly is to be used. The buoyant barge 10 is of substantially box-like shape (FIGURE 2) and is provided along each longitudinal side with a row of caisson Wells 13 having upper and lower guide openings (not shown) through which loosely extend elongated supporting members, here shown as caissons or tubular members 14, which may be alternately of different lengths in each row, for a purpose subsequently to be described. The interior of the barge 10 may be divided up by longitudinally disposed bulkheads or partitions (FIGURE 2) and by transverse partitions 16 so as to provide separate, watertight compartments 16. Associated with each of the caissons 14 on the upper barge is a suitable jack mechanism 17 for selectively effecting or restraining relative vertical movement between each of the caissons and the upper barge. The jack mechanism embodied in the Pointer copending application, Serial No. 143,627, is such a suitable mechanism and may be used for moving and maintaining barges and caissons in predetermined positions relative to each other.

The caissons 14 are grouped to include ground-penetrating caissons 18 and barge-connecting caissons 19 (FIGURE 5) which, as shown, are alternately spaced longitudinally along opposite sides of the barge 10 (FIG- URE 2). The caissons 18 extend freely through the lower barge 11, and for this purpose the latter also is provided with caisson wells 13 having upper and lower guide openings (not shown) through which the caissons 18 extend. The lower ends of the caissons 19, however, are rigidly secured to the lower barge 11. For this purpose, the lower ends of the caissons 19 (FIGURE 8) each extend through an opening or cut out portion in the top of the lower barge 11, and is welded to the bottom thereof, as at 20, and to the edges of such opening. The lower portion of each caisson 19 is closed otf by a watertight diaphragm plate 21 which may be coplanar with the top of the barge 11 and is welded, as at 20, to the side wall of the caisson 19.

The lower or ground-engaging barge 11 is also provided interiorly with a longitudinally and centrally disposed water-tight bulkhead or partition 23 (FIGURE 4), which may be welded as at 23 to the opposite end walls of the barge, with a central water-tight, transverse bulkhead 16, and also with additional longitudinal bulkheads 26 spaced inwardly from each side of the barge 11. Longitudinally spaced partitions 24 extend transversely between the bulkheads 23 and 26 and between the latter and the side walls of the barge 11 and may be Welded thereto as at 25. The bulkheads 16, 23, and 26 and the partitions 24 form interior compartments 27 and side and end wall compartments 27 separate from the caisson wells 13, While the partitions 24, the bulkheads 26, and the side walls of the barge 11 also form additional compartments about the lower ends of the caissons 19. Preferably, stiffening and reinforcing plates or webs 29' extend and are welded between the lower end of each caisson 19 and the walls of its compartment, and such plates 29 are provided with elongated openings 29. The lower ends of the caissons 19 and those portions of the bulkheads 26 and the partitions 24 bounding the compartments 27 and 27, separately from the caisson wells 13, are provided with openings 28 to permit free flow of water between all of the compartments 27 and 27' in each quarter section of the barge 11.

In order to submerge the lower barge 11 so that the same will firmly rest on the marine bottom, means are provided for introducing water into the compartments 27 and 27'. Additionally means are provided for withdrawing this water so as to raise or refioat the barge 11. As shown in FIGURE 8, this means includes positioning immediately above the diaphragm 21 of each of the caissons 19, a horizontal pipe or conduit 30 which at its outer end communicates with an opening 31 in the wall of the caisson 19 and at its opposite end has a depending elbow 32 which communicates as at 33 with the interior of the tubular caisson 19 below the diaphragm, which in turn communicates through openings 28 with compartments 27 and 27. An air actuated valve mechanism controls flow through the pipe 30 and includes a cylinder 34 (FIG. 13) in which is reciprocally mounted a piston that is operatively connected to a conventional type of flood valve in the housing 35. An air delivery pipe 36 communicates through a branch connection 37 (FIG. 11) with the interior of the cylinder 34 so as to control the opening and closing of the valve. The pipe or compressed air line 36 extends upwardly out of the top of the caisson and thence to a point adjacent the deck of the barge 10 so as to be operable by remote control means. A mesh or reticulated wire strainer 38 is positioned within the pipe 30 adjacent the inlet opening 31 to prevent foreign matter from being introduced into the barge 11 with the sea water. The flood valve housing 35 and its associated parts may be supported within the caisson 19 by the T-shaped bracket 39, which is welded, as at 40, to the diaphragm plate 21 when the parts are assembled (FIG. 13). Thus, it will be seen that when the flood valve in the housing 35 is moved from its closed to its open position and the opening 31 is submerged, sea water is introduced into the compartments 27 and 27 through the pipe 30' and its discharge outlet 33.

Also positioned within each of the caissons 19 and extending upwardly out of the top thereof is a compressed air and vent pipe or line 41 (FIG. 11) which at its lower end extends through the diaphragm plate 21, as at 42, to communicate with the space therebelow. Also mounted in each of the caissons 19 is a pipe or tubular member 43 (FIG. 12 which projects through the dia phragm plate 21 into the lower end of the caisson 19 and terminates in an enlarged bell portion 44 spaced a short distance above the bottom wall of the barge 11 so as to constitute means for expelling water from the compartments 27 and 27'. At its upper end, the pipe 43 is connected by an elbow 45 to a horizontal pipe 46 (FIG. 8) which communicates with an opening 47 in the caisson 19 spaced a considerable distance above the opening 31. A reticulated metal strainer 48 is positioned in the pipe 46 so as to prevent the introduction of foreign matter with any sea water which may pass therethrough into the compartments 27 and 27' of the lower barge 11'. Intermediate the length of the pipe 43 above the barge 11, a branch outlet pipe 49 (FIG. 12) is connected by a T- fitting St to the pipe 43. A one way check valve 51 is mounted in the pipe 49 so as to prevent the flow of the water into the pipe from outside the barge but permits the escape of water from the barge through the pipe 49. The end of the pipe 49 communicates with an opening 52 in the wall of each caisson 19 on a level with the openings 31, and a reticulated metal strainer 53 is positioned in the pipe 49 adjacent the opening 52 (FIG. 12). A threaded closure plug 54 (FIG. 9) in the pipe 49 is arranged when removed to provide access to the interior of the check valve housing for inspection purposes. The lower end portion of each of the caissons 19 above the lower barge 11 has a plurality of openings or ports 55 to facilitate the introduction of sea water and the discharge of the same from within each of the caissons 19 above the closure plates 21.

As previously stated, the compressed air pipe 36 controls the operation of the flood valve in the housing 35 while compressed air may be introduced into the barge through line 41 so as to force the water out from the compartments through the pipe 43. Pipe 41 also constitutes an air vent for allowing the escape of air from the barge 11 when the same is being flooded. The pipes 36 and 41 may have their outer ends positioned, as shown in FIGURE 1, adjacent the top or deck of the barge 10 and are provided with suitable operable valve means as at 56 and 57 for selectively controlling the flow of air through these pipes.

In the modified form of the invention shown in FIG- URE 14, water in the compartments 27 and 27' of the barge 11 may be withdrawn therefrom so as to lighten the barge 11 by mounting in each of the caissons 19, a submergible pump 58 which is electrically connected through the line 59 with suitable switch means (not shown) positioned on the upper barge 10 and preferably adjacent to the means 56 and 57, previously described. The pump 58 communicates through a horizontal pipe 60 and an elbow 61 with a vertical suction pipe 62 which is provided at its lower end with a bell mouth 63 spaced above the bottom shell of the barge 11 so as to allow the withdrawal of water in the compartments 27 and 27' when the pump 58 is actuated. A Strainer 64 is positioned in the horizontal pipe 60. An outlet conduit 65 also communicates with the pump 58 and has a portion 66 extending upwardly through the diaphragm plate 21 so as to communicate with a check valve 67 which in turn communicates with a pipe 68 that extends outwardly through an opening 69 to discharge the water overboard from the compartments 27 and 27 when the pump 58 is in operation. An air vent pipe or line 70 extends downwardly in the caisson I19 and through the plate 21, so as to communicate with compartments 27 and 27.

Any

air pressure line or pipe 71 communicates with an air cylinder 72 having a piston operatively connected to a reciprocating valve in the valve housing 73 which in turn communicates on one side with an intake pipe 74 and on its opposite side with a discharge pipe 75 that extends downwardly through the plate 21 for communication with the compartments 27 and 27 The outer end of the pipe 74 terminates in an opening 76 in the caisson wall and may be provided with a strainer 77. A valve in housing 73 controls the admission of the water into the compartments 27 and 27' of the barge 11 when the opening 76 is submerged.

In operation, the barges are normally in their floating position and stacked as shown in FIGURE 1 so as to be easily towed to the site of operation. In this position it will be noted that the openings 31 are submerged. The barges may be maintained in this stacked position by the jack mechanisms 17 or other suitable mechanical means engaged with the caissons 19. When the barge assembly reaches the site of operation, the lower or ground-engaging barge 11 is submerged so as to firmly engage marine ground by opening the flood valves 35 and venting air through the pipes 41, both of which are controlled from the barge 10. Suflicient water is permitted to enter the compartments 27 and 27' through the intake pipes 30 (FIG. 13) to a level where the barge 11 will be submerged deep enough so that the water will now enter the intake pipe 46 and opening, 47, above the pipe 30 (FIG. 8). The flood valves 35 may then be closed and water will continue to enter the compartments 27 and 27' through the pipes 46 in the caissons 19. In other words, the valves in the housings 35 preferably are closed as soon as the outside water starts to enter the intake pipes 46. Air in the compartments 27 and 27 escapes or is vented through the pipes 41 (FIG. 11) to the atmosphere. The rate of descent of the barge 11 is controlled by operation of the jack. mechanisms 17 on the caisson 19', and the jacks 4, the caissons 18 are also operated to move the latter downwardly with the caissons 19 during the submerging operation.

When the barge 11 is brought in engagement with the marine ground 79 (FIGS), the jacks '17 associated with the ground-penetrating caissons 18 are actuated so as to force the caissons 18 into the submerged ground as at 80 in order to firmly maintain the supporting barge 11 anchored in a fixed position and thus prevent lateral displacement of the assembly, as well as to provide additional support for the barge 10. All of the jacks 17 are now actuated to raise the barge 10 on all the caissons above the level of the water 81 so that the upper barge is converted into a working platform or superstructure on which may be conveniently mounted means for drilling oil or other wells, driving of piles, building of permanent structures, temporary and permanent dry docks, or in fact any kind of working platform for marine operations or the like. The barge 10 is maintained in its working position above the water either by the jacks 17 or by suitable mechanical gripping devices engageable with the caissons and which may readily be released when the work is completed. It will be manifest that while normally the barge 10 which is substantially similar in construction to the barge 11 is not submerged, it may be provided with compartments and means for introducing water and air similar to the means for controlling the submergence of the barge -11. Thus, the assembly may then be used for dry dock purposes and the barge 10 submerged a sufiicient distance to receive a boat in order to subsequently be raised above the water so as to operate as a dry dock for marine repairs.

The barge assembly is returned to its floating position (FIG. 1) by reversing the action of the jacks 17 so as to lower the barge 10 to again float in the water. Air is then introduced into the interior of the submerged barge' 11 through the pipes 41 in'each of the caissons 19 and under suflicient pressure to force the water upwardly through the bell mouths 44 of the pipe 43 (FIG., 12) and
